  • Digital-to-analog converter using capacitors and operational amplifier
    Patent number: 7355543
    Abstract: A digital-to-analog converter using capacitors and an operational amplifier, which can be highly integrated due to its small area and which can rapidly perform a stable converting operation. The digital-to-analog converter includes a data input unit, a first conversion unit, a second conversion unit, and a signal output unit. When digital data is input to the data input unit, the data input unit is connected to the first conversion unit or the second conversion unit. The first conversion unit charges a first charging capacitor with a voltage corresponding to the input digital data and distributes the charged charges to a first distribution capacitor. The second conversion unit charges a second charging capacitor with the voltage corresponding to the input digital data and distributes the charged charges to a second distribution capacitor.
